Answer 1

The following code will solve the problem by mapping to the correct imagecreatefrom* function or throw an exception with the invalid image type.

switch(strtolower($stype)) {
            case 'gif':
                $simg = imagecreatefromgif($source);
                break;
            case 'jpg':
            case 'jpeg':
                $simg = imagecreatefromjpeg($source);
                break;
            case 'png':
                $simg = imagecreatefrompng($source);
                break;
            default:
            throw new \Exception('invalid image type :'.$stype);
            break;
        }
